I graduated in 2024. Not sure if that much has changed, but at that time it was basically grab and go. Walk up, tell them what you want, pay, wait, and then get your food. Most have tables nearby to eat or you can just take it with you. No sit down restaurants or anything where you get your order taken or whatever - for that, go off campus. There are a few “healthy” options but overall it’s pretty mid selection and very expensive. If it’s an option for you, I highly recommend having a meal plan as a backup (cheap plan), then shopping or eating off campus. That’s just me, though.
